Two coins were tossed 10 times. The results are shown in the table below.
result tableThe first column has the word Toss in the 1st Row and the word Results in the second row. The second column has the number 1 in the 1st Row and the letters H H in the 2nd Row. The third column has the number 2 in the 1st Row and the letters T T in the 2nd Row. The fourth column has the number 3 in the 1st Row and the letters H T in the 2nd Row. The fifth column has the number 4 in the 1st Row and the letters T H in the 2nd Row. The sixth column has the number 5 in the 1st Row and the letters H T in the 2nd Row. The seventh column has the number 6 in the 1st Row and the letters H H in the 2nd Row. The eighth column has the number 7 in the 1st Row and the letters T H in the 2nd Row. The ninth column has the number 8 in the 1st Row and the letters T T in the 2nd Row. The tenth column has the number 9 in the 1st Row and the letters T H in the 2nd Row. The eleventh column has the number 10 in the 1st Row and the letters H T in the 2nd Row.
What is the experimental probability that at least one of the coins landed on heads? Express the probability as a decimal.

To find the experimental probability that at least one of the coins landed on heads, we need to find the proportion of tosses where at least one coin shows heads. Looking at the result table, we see that in all 10 tosses, there are four tosses where both coins show tails (rows 2, 8, 9, and 10). This means that in six out of the 10 tosses, at least one coin landed on heads. Therefore, the experimental probability is 6/10 or 0.6.
